EventService: Add event log support with inotify

Add event logs support
 - Event log monitor by adding inotify on redfish log file.
 - Read event logs from "/var/log/redfish" file.
 - Filter the event logs using configured settings.
 - Format the event log data as per Events schema.
 - Send event log information to subcribed client.

Tested:
 - Added new event log subscription with filters
   and verified the event logs on event listener.
 - Ran redfish validater successfully.
 - Disabled BMCWEB_ENABLE_REDFISH_DBUS_LOG_ENTRIES
   and build successful.

   Event on listener looks as below:
{
   "@odata.type":"#Event.v1_4_0.Event",
   "Events":[
      {
         "Context":"CustomText",
         "EventId":"94787",
         "EventTimestamp":"1970-01-02T02:19:47+00:00",
         "EventType":"Event",
         "Message":"Memory ThermTrip asserted: .",
         "MessageArgs":[
            ""
         ],
         "MessageId":"OpenBMC.0.1.MemoryThermTrip",
         "Severity":"Critical"
      }
   ],
   "Id":"3",
   "Name":"Event Log"
}
